When Israel signed a ceasefire deal with Hamas in Gaza on January 15, the agreement was structured in three phases. Phase one, a six-week period in which Hamas would release hostages in return for Israel releasing Palestinians detained in its jails, ended on March 1.

Foreign Minister Gideon Saar said on Tuesday Israel was ready to proceed to the second phase of the Gaza ceasefire deal, as long as Hamas was ready to release more of the 59 hostages it is still holding.

Qatar, a key negotiator of the ceasefire, accused Israel of violating the deal. The U.N. relief chief said aid access must be allowed under international law.
